[R] calculate slope of line

[Katrin Fleischer]

Dear All,

I fear that this is a really easy question but I do seem to go around in 
circles..
I have 2 points on a plot and would like to calculate the slope of the 
line drawn through these 2 points.

that cant be so hard?!

Thank you in advance,
Katrin
